Have you ever had to reject what would have been an amazing picture because the image was out of focus, despite using the autofocus function correctly at the moment of the shot? Well, we have. But now we’ve finally come across a solution other than sending in the camera and lens for service. With Datacolor’s Spyder LensCal you can check if the focus of your lens is optimum, and adjust it if not.
Over the years we have had to send both camera body and lenses for re-calibration now and then, since with heavy use the focus seems to go slightly off. With a fairly low investment, approx. EU 65 (including VAT) you can check and adjust your lenses yourself, providing that your camera has the necessary function for this. It’s called Autofocus Microadjustment (AFMA), and it’s supported in most professional cameras.
